2500m^3高炉开炉及达产实践

Practice of Blowing-in of 2500m^3 BF

对南钢2500m3高炉开炉及快速达产进行了总结。南钢2500m3高炉采用上罐固定中心卸料式串罐无料钟炉顶、软水密闭循环冷却、陶瓷杯+高导热炭砖炉底、铜冷却板结合铜冷却壁等先进技术。在开炉过程中,选择合适的炉料和配比,进行装料测试,确立了合适的装料制度和操作参数,使得高炉开炉顺利并实现了快速达产。

The experiences on blowing-in and reaching target output of 2500m3 BF in NISCO are summarized. Some advanced technologies were applied such as bell-less top of PW technology, soft water closed-circulation cooling system, ceramic cup plus carbon blocks, copper cooling plate combining copper stave. At the blowing-in period, a series measures, such as proper selection of blowing-in burden and blending ratio, charging measurement, proper charging regulations and operation parameters, make the furnace start succ...
